There are two basic models of criminal justice. The "crime control" model suggests that repressing crime should be the top priority of any society's criminal justice system. It values strong police presence and activity, the presumption of guilt, and the vindication of victims' rights. The "due process" model values due process of law, the presumption of innocence, and correct legal procedure. Under the "due process" model, people are subject to punishment only after lawful legal proceedings that have ensured the protection of their rights. Under the "crime control" model, sufficient evidence alone is enough to convict, regardless of the legal proceedings which lead to the convictions. The due process model is best suited to deal with crime problems of the future. It ensures that governmental and corporate entities are not able to take advantage of individuals accused of crimes. Issues of privacy, coercion and corruption are better dealt with under the due process model than the crime control model.

I assume that you are asking about Herbert Packer's two models of the criminal justice system. If so, I would argue that the crime control model is more likely to be chosen to deal with crime problems of the future.

The reason for this is that there are more and more pressures on the criminal justice system even as the system is being given fewer and fewer resources. For example, the crime control model argues that there should be more plea bargains and fewer jury trials. I believe that this will look more and more attractive as the court system becomes more and more overloaded. Similarly, the police are more likely to have technologies that will allow them to intrude more into people's lives. Their ability to do so will fit more closely with the crime control model than with the due process model.

So, I believe that the crime control model will be increasingly used in the future as a way to deal with crime more efficiently.
